After transcription, where is the mRNA typically transported for translation?

Explanation:
Transcription happens in the nucleus, and the mRNA must leave through nuclear pores to be read by ribosomes. The translation machinery is in the cytoplasm, so mRNA is transported there for reading and protein synthesis. Translation can occur with free ribosomes in the cytosol, and some proteins destined for secretion or membranes are synthesized on ribosomes attached to the rough endoplasmic reticulum—also part of the cytoplasmic region—after the mRNA has reached the cytoplasm. The Golgi apparatus and the ER are involved later in processing and sorting the protein, not in the initial transport of the mRNA for translation.
